Loading contentThe visual layer over the knowledge graph. Every map here is drawn from real, measured coordinates — a star or galaxy appears only where the data places it — turning the catalogue into a sky you can navigate, from the constellations overhead to the far reaches of the Local Group.
878 stars brighter than magnitude 4.5, at their measured positions.
The positional charts — the all-sky star atlas, the constellation atlas, the Messier and deep-sky atlases, and the bright-star map — each drawn as scalable vector graphics from the real measured coordinates of the stars and deep-sky objects.
5 entriesThe interactive and three-dimensional-ready explorers — the Solar System, the Milky Way, the Local Group, the galaxy atlas, and the planet, moon, exoplanet, and distance-scale explorers — that browse the real object collections of the graph.
9 entriesThe layers drawn on top of the maps — constellation lines, observing conditions, and the JWST, Hubble, Gaia, and telescope field-of-view overlays — that add context without ever inventing a position.
6 entriesA whole-sky chart plotting every catalogued star at its real right ascension and declination, sized by apparent magnitude. Rendered as scalable vector graphics directly from the star catalogue's measured coordinates — nothing is invented; a star appears only where the data places it.
A naked-eye view of the sky showing only the brightest stars, ranked by apparent magnitude. The stars that anchor the constellations and guide the eye across the night.
The eighty-eight official constellations, each mapped by the real positions of its brightest stars. A gateway from the familiar patterns of the night sky into the stars, myths, and deep-sky objects each region holds.
A map of the catalogued deep-sky objects — galaxies, nebulae, and star clusters — drawn from their measured right ascension and declination, with symbols scaled by angular size. The wider sky beyond the naked-eye stars.
An explorer of cosmic distance and scale — from the nearest stars to the edge of the observable universe — built on the rungs of the cosmic distance ladder. Prepared to visualise the vast, logarithmic reach of the cosmos honestly, with distances drawn only from measured indicators.
An explorer of the confirmed planets beyond the Solar System, drawn from the measured exoplanet catalogue — organised by host star, detection method, size, and orbit. The worlds of other suns.
A browsable index of catalogued galaxies — spirals, ellipticals, and irregulars — organised by morphology and distance. The building blocks of cosmic structure, each linked to its place in the knowledge graph.
An explorer of our galactic neighbourhood — the Milky Way, Andromeda, Triangulum, the Magellanic Clouds, and the dozens of dwarf galaxies bound with them into the Local Group. Prepared for a three-dimensional map of the nearby universe.
A chart of the Messier objects — the nebulae, clusters, and galaxies of Charles Messier's eighteenth-century catalogue — each placed at its real celestial coordinates and sized by its apparent extent. The classic target list for a first tour of the deep sky.
An explorer of the structure of our own Galaxy — its discs, bulge, bar, spiral arms, and halo, and the Sun's place within them. Prepared for a three-dimensional rendering of galactic structure; today it maps the anatomy of the Milky Way onto its components.
An explorer of the moons of the Solar System — from Earth's Moon to the ocean worlds of Jupiter and Saturn — organised by their host planet and physical character.
An explorer of the New General Catalogue and its deep-sky objects, organised by type, constellation, and catalogue. The deep sky beyond the Messier list.
An explorer of the planets — their sizes, orbits, atmospheres, and moons, drawn from measured planetary data. From Mercury's scorched rock to the ice giants of the outer system.
An explorer of the Sun's family — the planets, their moons, and the small bodies between them. The data model carries each body's real orbital and physical parameters and is prepared for a future interactive three-dimensional scene; today it presents the ordered, to-scale structure of the system.
Each atlas view and overlay is a first-class knowledge-graph entity resolved through the Scientific Data Engine. Positional maps are rendered directly from the measured right ascension and declination already stored in the star and deep-sky catalogues; object counts are computed from the live collections, never hard-coded; and three-dimensional views are prepared as architecture rather than fabricated scenes.
